Patent SE-8406173-L (SE)
Inventor: RANNENBERG G C
IPC: F25B9/00
Filed: 1984-12-05
Abstract: A high efficiency air cycle air conditioning system (10), driven and charged by a gas turbine engine (15), operates in a closed-loop, Brayton cycle. The system includes a main (bootstrap) compressor (75) discharging to a sink heat exchanger (85) which in turn discharges to a regenerative heat exchanger (110). Air is ducted from the regenerative heat exchanger to an expansion turbine (120) where the air is chilled and then ducted to load (20). Air exhausted from the load is again ducted through the regenerative heat exchanger where the load exhaust air precools turbine inlet air. The capacity (operating pressures) of, and input power to the system are controlled by modulation of charge air provided to the system from the gas turbine engine and if desired, may be further controlled by selective bleeding of air from the system, selective bypassing of the system turbine with refrigerant, or modulation of shaft input power to the main compressor.

Abstract: A brake system intended for automotive vehicles provided with a brake pressure transmitter (1) which is linked to the wheel brakes through pressure medium lines, and with sensors (19 to 22, 24) which are responsive to the brake pressure or to the behavior of rotation of the wheels and by means of which the braking effect at the wheels brakes is detectable. Furthermore, separating valves (SO1, SO2, SO3, SO4, SOHA ) for shutting off the flow of pressure medium in one switching position are incorporated in the pressure medium paths leading to the wheel brakes. A monitoring circuit (3', 25') to which the sensor signals are transmittable recognizes the failure of one wheel brake and thereupon automatically commutates the separating valve located in the pressure medium path leading to the wheel brake which has failed into a valve position locking the flow of pressure medium.

Abstract: The mould surfaces are given different frictional characteristics according to the plastic type. The plastic is better able to take up the shape of the mould and achieve the desired thickness variations. - Friction measurements are carried out using the following equipment: A carriage (inside an oven)is pulled over a table via two wheels and a motor. The plastic film is tensioned on the carriage and a model of the mould material is placed on the film. This is connected to a force measuring unit. The loading is changed by changing the weight.

Abstract: A dry compliant overlapping seal for a phosphoric acid fuel cell preformed of non-compliant Teflon to make an anode seal frame that encircles an anode assembly, a cathode seal frame that encircles a cathode assembly and a compliant seal frame made of expanded Teflon, generally encircling a matrix assembly. Each frame has a thickness selected to accommodate various tolerances of the fuel cell elements and are either bonded to one of the other frames or to a bipolar or end plate. One of the non-compliant frames is wider than the other frames forming an overlap of the matrix over the wider seal frame, which cooperates with electrolyte permeating the matrix to form a wet seal within the fuel cell that prevents process gases from intermixing at the periphery of the fuel cell and a dry seal surrounding the cell to keep electrolyte from the periphery thereof. The frames may be made in one piece, in L-shaped portions or in strips and have an outer perimeter which registers with the outer perimeter of bipolar or end plates to form surfaces upon which flanges of pan shaped, gas manifolds can be sealed.

With a piston (3) capable of axial displacement, the cylinder (2) is divided into two sub-spaces (6, 7). The space (10) communicates with the aforementioned first sub-space (6) via a first openable and closable valve (11a). The second sub-space (7) communicates with the aforementioned first sub-space (6) via a second openable and closable valve (13a). A control device (12) actuates the openable and closeable valves (11a, 13a), so that the second valve (13a) is opened when a force (F) acting upon the end of the piston rod (8) has forced the piston (3) in a direction towards the first end wall (4) and into a predetermined position. The second valve (13a) is closed again once pressure equilibrium has been achieved between the sub-spaces (6, 7). The first valve (11a) is opened for a period of sufficient duration to permit pressure equilibrium to be achieved between the second sub-space (7) and the enclosed space (10). After a predetermined period has elapsed after the force (F) acting against the end of the piston rod has ceased to be applied, the aforementioned second valve (13a) opens, when the piston (3) returns to its initial position. Once the piston (3) has reached its initial piston, the first valve (11a) is opened.

Abstract: One end of a passenger bridge or a goods-handling device of mobile type can be expediently and securely connected to a door on a craft, especially an aircraft, by determining the position of the door in relation to a reference point on the craft and storing it in a computer system. Furthermore, the absolute position of the door when the craft has come to a halt and the passenger bridge or the goods-handling device is to be connected, is determined by measuring the distance from a reference point on the ground to the craft. Finally, the computer system guides the passenger bridge to the door of the craft, the position of the end of the passenger bridge or the goods-handling device being determined during the guiding operation and inputted into the computer system. To further shorten the connection time, the passenger bridge or the goods-handling device is advantageously guided to an initial position of connection in the vicinity of the craft, in which position the end of the passenger bridge or the goods-handling device is aligned with the expected position of the door and disposed at a small distance therefrom, before the craft has come to a halt.
